Pass attended the University of Georgia, where he played football as a running back, quarterback, receiver, and kick returner. Before his freshman season, he was drafted by the Florida Marlins in the 1996 Major League Baseball draft, and played that summer in the Marlins' farm system. He played again in the Marlins' minor league system before his sophomore and junior seasons in 1997 and 1998.

Pass was drafted by the Patriots as a running back in the seventh round of the 2000 NFL Draft. He spent two weeks on the Patriots' practice squad in 2000 before being activated. In his first start on November 19, Pass played as a running back, wide receiver, and special teamer, recording 39 rushing yards, 16 receiving yards, and two special teams tackles. In the 2002 off-season, Pass put on 35 pounds and made the transition to fullback, where he would start for the 2004 team. In 2005, with top rusher Corey Dillon injured, Pass would see time as a running back, recording a career-high 245 rushing yards that season. However, Pass himself would miss time in 2005 with a hamstring injury suffered against the Buffalo Bills on October 31. In 2006, Pass continued to struggle with the injury, being placed on the Physically Unable to Perform list, and being limited to just three games before going on injured reserve. Pass also saw time as a kick returner in his time with the Patriots, returning 36 kickoffs for 745 yards.

Pass signed with the Houston Texans before the start of the 2007 NFL season; the Texans released him on August 29, 2007. Pass was signed by the New York Giants on November 20, 2007, playing in one game before being released on November 27, 2007.

After spending the 2008 NFL season out of football, Pass signed again with the Patriots on June 4, 2009. He was released a week later, on June 11 and retired from the NFL.

In 2012, Pass became the head coach of the Boston Freedom Fighters, a team in the new Professional Developmental Spring League called the "National Spring Football League".
